The couple declared notice on Wednesday, the magazine reported. The notice allows the pair to marry after Sept. 30 through October of next year.
Old Marylebone Town Hall was the site of the music legend’s 1969 wedding to first wife Linda.
“It was all a bit last minute. I had no prior warning,” Superintendent Registrar Alison Cathcar told People of the couple’s notice to wed. “They were lovely, very relaxed and very charming and clearly in love with each other,” she said.
The rocker, 69, proposed to Shevell, 51, a transportation heiress, in April with a reported $650,000 engagement ring.
This will be Shevell’s second marriage and McCartney’s third. His first wife, Linda, died of cancer in 1998 at age 56. They had four children together, including designer Stella McCartney. The singer’s second marriage to Heather Mills, which produced daughter Beatrice, ended in a messy divorce in 2008 and the famously frugal Beatles singer had to fork over a reported $35 million.
That hasn’t stopped him from falling in love again and reportedly rebuffing a prenuptial agreement.
Shevell’s own wealth is only part of the reason McCartney is eschewing a prenup, Popeater’s Rob Shuter told ABCNews.com. “Paul is saying, ‘This girl is not Heather,’” he said.
“She’s a very, very different lady than Heather Mills,” Shuter said. “She’s incredibly wealthy and successful in her own right.”
